The Sigma 50mm f/1.4 DG DN Art Lens for Sony E is a full-frame prime lens engineered for photographers who demand both optical excellence and blazing autofocus performance. Built around a sophisticated 14-element, 11-group design featuring three aspherical elements and one SLD glass element, it delivers razor-sharp images with outstanding correction of astigmatism and field curvature across the entire frame.
With its bright f/1.4 maximum aperture and Sigma Art series pedigree, this 50mm lens excels at portraiture, landscapes, street photography, and low-light shooting on Sony E-mount mirrorless cameras. The newly developed HLA (High-response Linear Actuator) motor ensures fast, precise, and whisper-quiet autofocus, making it equally at home shooting stills or video.
Key features
- Ultra-bright f/1.4 aperture gives you exceptional shallow depth-of-field control and the ability to shoot confidently in low-light environments.
- HLA High-response Linear Actuator focusing motor delivers unprecedented autofocus speed, precision, and silent operation — ideal for tracking moving subjects and video work.
- Advanced optical formula — 14 elements in 11 groups with 3 aspherical lenses and 1 SLD element — effectively suppresses astigmatism, field curvature, and other aberrations for corner-to-corner sharpness.
- Rounded 11-blade diaphragm produces beautifully smooth, circular bokeh for creamy background separation in portrait and selective-focus shots.
- Dust & splash-resistant construction with a brass bayonet mount and water/oil-repellent front element coating keeps you shooting reliably in challenging outdoor conditions.
- Versatile physical controls — including an aperture ring with click/lock switch and a customisable AFL button — offer pro-level handling flexibility straight from the lens.

Frequently asked questions
Is the Sigma 50mm f/1.4 DG DN Art compatible with APS-C Sony E-mount cameras?
Yes. Although designed primarily for full-frame Sony E-mount mirrorless cameras, the lens is fully compatible with APS-C models as well, where it provides an equivalent focal length of approximately 75mm.
How does the HLA autofocus motor benefit video shooters?
The HLA (High-response Linear Actuator) motor is engineered for high-speed, high-precision, and near-silent focusing. This makes it excellent for video recording, as it tracks moving subjects smoothly without generating audible noise that could be picked up by a microphone.
Can the Sigma 50mm f/1.4 DG DN Art be used in wet or dusty conditions?
Yes. The lens features a dust- and splash-resistant construction, a brass bayonet mount for added durability, and a water- and oil-repellent coating on the front element, making it suitable for use in harsh environmental conditions.
